50# fuel injectors

[1fstss]

came out of my LT1 replaced them with 80# injectors. worked great!! not sure of the brand.
these are rated at 50# at 43.5lbs of fuel pressure so in a LS1 they are like 55# or so. looking to get 300obo for them

damn good luck with the sale. makes my little 30#s look small

do you know if they are high or low impedence?

[1fstss]

they are high impendance. they work with the stock ecu and dont require a driver.

[Caveman]

i know you cant use low impedence ones on stock ecu.. can i use high impedence on aftermarket ecu? (FAST XFI)

[1fstss]

i believe so. the AEM ECU is highly adjustable, i dont see why they wouldnt let you... but hell im running a stock ECU and 80lb injectors with no driver

i emailed fast, they recomend me sticking with what i have (accel 32lbhr) until i start makin more power.. i guess runnin too big of an injector could be slightly problematic..which i can kinda see..

You want to make sure that you're not gas-washing the oil. B had an extreme case, but a good example of the pandimonium that can occur if too much fuel's shot in.

i was thinking maybe more like trying to put on too big of a carb or soemthing.. lose a lot of response, rough (or more so) idle..stuff like that..
